Abstract
The utility model relates to a main switch for a car power source, comprising a base 18, an outer shell, coils and a shaft core 13. The main switch for a car power source is characterized in that the coils arranged at the bottom of the outer shell comprise an absorbing-pulling coil 15 and an insurance coil 16, and the absorbing-pulling coil is connected with a power source by a normally close contact 9; the upper and the lower parts of the shaft core are respectively sheathed with a pressure spring 7 and a return spring 8, and a stop positioning shaft core and a balancing bracket 10 are arranged above the pressure spring; the shaft core is fixed with a movable contact 4 and a shifting block for controlling the switching of the normally close contact, and two fixed contacts 6 which are communicated with the negative electrode of the power source are arranged inside the outer shell at the place corresponding to the movable contact. The utility model has the advantages of simple structure, convenient adjustment, favorable quality, etc.
Description
The utility model relates to a kind of car electrics accessory, particularly a kind of automobile power source master switch.
At present the battery feed master switch that uses has two kinds of mechanical type and electromagnetic types, though mechanical type low price, the connection lead is long, line loss is big but have, the contact point pressure drop greatly, easily causes deficiencies such as cold-starting difficulty, and the center bearing bracket of general electromagnetic power-supply general switch is a copper spare bow-shaped structural, often because of machining deformation is big, brings difficulty to assembling and setting, make production efficiency low, second-rate.
The purpose of this utility model designs simple, the easily manufacturing, easy to install of a kind of structure exactly, and quality is the electromagnetic type automobile battery main switch preferably.
The purpose of this utility model realizes by following structure: the automobile power source master switch, include base, shell, coil and axle core, its principal character is: the coil at outer casing bottom includes pull in winding and hold-in winding, pull in winding is connected with power supply by normally closed interlock, at upper and lower holddown spring and the return spring of being with of axle core, the support that stop locating shaft core is arranged above holddown spring, the shifting block and the moving contact of also intrinsic control normally closed interlock break-make on the axle core, intrinsic two fixed contacts of connecting with power cathode of moving contact correspondence position in the enclosure.
The utility model compared with prior art has simple, less, the easy manufacturing of parts in addition of structure, Electromagnetic Control, installs and uses advantages such as more convenient, and service quality, life-span are better.
Description of drawings of the present utility model is as follows.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model;
Among the figure:
1 loam cake, 2 lower casings, 3 bakelite spares, 4 moving contacts
5 insulated rings, 6 fixed contacts, 7 holddown springs, 8 return springs
12 cores of 9 normally closed interlock 10 supports, 11 shifting blocks, 13 yoke plates, 14 insulation boards, 15 pull in windings, 16 hold-in windings, 17 lower magnetic poles, 18 bases, 19 control connector lugs, 20 electrode strip leading-out terminals, 21 sealing rings, 22 pilot holes, 23 prerotation vanes.
Below in conjunction with drawings and Examples structure of the present utility model and principle are further described:
As shown in Figure 1; The utility model base 18, shell, coil and axle core, it is characterized in that: the coil at outer casing bottom includes pull in winding 15 and insurance coil 16, pull in winding is connected with power supply by normally closed interlock 9, at upper and lower holddown spring 7 and the return spring 8 of being with respectively of axle core, the balance bracket 10 that stop locating shaft core is arranged above holddown spring, the shifting block 11 and the moving contact 4 of also intrinsic control normally closed interlock break-make on the axle core, intrinsic two fixed contacts of connecting with power cathode 6 of moving contact correspondence position in the enclosure; More square for Installation and Debugging, overcome the disadvantage that bow-shaped support brings, support 10 can be made of pillar and the copper billet with bakelite spare 3 integrated through injection molding; Stable in order to use, reliable, there is being a pilot hole 22 to match on the copper billet, as shown in Figure 2 with prerotation vane 23 on the shifting block; Operation principle of the present utility model as shown in Figure 3, after control switch K closure, positive source arrives pull in winding 15 through control connector lug 19, make normally-closed contact 9 closures, this moment, the pull in winding energising produced strong magnetic force, magnetized axis core 12 lower magnetic poles magnetization 17 attracts each other, and the axle core overcomes return spring 8 pulling force and moves down.Because moving contact 4, switching shifting block 11, compression spring 7 is fixed on the axle center, and when the axle center was moved down by magnetic force, above part moved down simultaneously.When moving contact contacts with the electrode strip fixed contact, shifting block 11 switches normally-closed contact 9 and disconnects, spacing is dwindled between axle center and the lower magnetic pole at this moment, corresponding need reduce with magnetic force, positive source by hold-in winding 16 to normally-closed contact last slice, because of last slice by Luo Ding ground connection, so producing magnetic force, the hold-in winding energising continues the axle center is contacted with lower magnetic pole toward drop-down, overcome holddown spring pressure simultaneously, and make moving contact that the above pressure of 2N be arranged and contact moving contact, connect whole power consumption equipments loop this moment.
When power supply drop to 5V when following because the reducing of magnetic force, the power of return spring and holddown spring is during greater than magnetic force, battery main switch can cut off general supply automatically, reminds operating personnel to note, can not restart simultaneously.
